Rescuing type of robbery before time adjustment (8,6)
I believe the answer is:
daylight saving
'time adjustment' is the definition.
The answer and definition can be both related to time as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'rescuing type of robbery before' is the wordplay.
'rescuing' becomes 'saving' (saving is a kind of rescuing).
'type of robbery' becomes 'daylight' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'before' says to put letters next to each other.
'saving' after 'daylight' is 'DAYLIGHT-SAVING'.
Can you help me to learn more?
(Another definition for daylight saving that I've seen is " Practice of moving time forward an hour in spring".)
